The two substrates of this enzyme are L-gulonatic acid and oxidised nicotinamide adenine dinucleotide phosphate (NADP+). Its products are D-glucuronic acid, reduced NADPH, and a proton. [1] [2] [3] [4]

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is L-gulonate:NADP+ 6-oxidoreductase. Other names in common use include aldehyde reductase, L-hexonate:NADP dehydrogenase, TPN-L-gulonate dehydrogenase, aldehyde reductase II, NADP-L-gulonate dehydrogenase, D-glucuronate dehydrogenase, D-glucuronate reductase, and L-glucuronate reductase (incorrect). This enzyme participates in pentose and glucuronate interconversions and ascorbate and aldarate metabolism.
